Care to provide a patch for them?

They now made VLC's configure error out when compiling with FFmpeg [1],
because they currently lack time [2] to fix this the way you suggest
and Libav doesn't return this error.

Thus I think it would be better to reduce this to a warning for the
time being and maybe add a FF_API_* changing it to an error after
the usual deprecation period.

Best regards,
Andreas
